Keithley 2400 Problems

Bommelchen — Wed, 13 Aug 2014 07:55:07 GMT

Hi,

I'm trying to run a Keithley 2400 SourceMeter with LabView using the latest driver (Keithley 24XX) and the example VI "Keithley 24XX Read Single.vi".

After selecting the GPIB Adress I run the program and Labview throws the following error message:

Error -1074000000 occurred at Keithley 24XX.lvlib:Error Query.vi

Possible reason(s):

Instrument reports:
-113,"Undefined header"
-230,"Data corrupt or stale"
-420,"Query UNTERMINATED"
0,"No error"

Complete call chain:
Keithley 24XX.lvlib:Error Query.vi
Keithley 24XX.lvlib:Read (Multiple Points).vi
Keithley 24XX.lvlib:Read (Single Point).vi
Keithley 24XX Read Single.vi

I also have a Keithley 2000 Multimeter up and runing with it's latest driver and the example program and it works just fine.

What could be the problem?

Thanks in advance!

You say latest version, which version is listed in the Keithley 24XX Readme.html?

I just installed it yesterday by using the NI Driver Finder:

Driver Revision: 1.2.3

Original Release Date: 12/15/06

Current Revision Date: 02/05/2014

That is the correct one.

I have no idea what goes wrong and have no testinstrument at hand.

can you send the IOtrace what happens on the bus?

the initialize seems to work, and the rest should also work

OK i just used an other Keithley 2400 from our lab and this one works fine.

Maybe it's a problem with the Firmware because when I select the GPIB adr on the new instrument it asks for SCPI or 488. The old one just asks for the GPIB Adr.

However, I'll just use the new one and update the firmware on the old one maybe sometime in the future 🙂

Me again:

I updated the Firmware to Rev. C32 and now it works!

Hello,

I am using Labview 2013 to try to control a Keithley 2400 Sourcemeter by GPIB_USB. I am using the labview drivers from the Keithley 24XX drivers package which I downloaded from the "Find Instrument Drivers" in Labview. My target is to measure the voltage by having constant current. is there any Labview program which I could use or modify? because I'm totaly new in Labview.

BR,

There should be examples with those drivers. If not, then go through the driver palette and think about what you would do manually. Find those functions to do what you would do manually.

Re: Keithley 2400 Problems

Albert.Geven — Thu, 09 Oct 2014 19:48:14 GMT

use the example

In the menu goto Help / Find examples

In the example finder goto Hardware input output / instrument drivers / LabVIEW plug and play

try Keithley 24XX Output List and Acquire.vi

Thank you for your reply. I tried Keithley 24XX Output List and Acquire.vi , but when I run the file there are errors as: Sub VI is missing. is there any way to solve this?

Is your NI Software up to date? I had the same problem once and I used the NI Update Service to update the Software.

Which SubVIs are missing?

Re: Keithley 2400 Problems

mehrkh — Fri, 10 Oct 2014 11:24:34 GMT

Sub VI missing is solved ba replacing the file. When I run the keithley 24xx output list and acquire.vi i have an error. you can see in attached file.

The error is that you ask something from the K2400 that is not allowed.

Could it be that the combination of 0.1 Amp compliance and 0.1 Volt is not allowed?

What is the Voltage limit?

It is possibkle that the order in which the limits and source voltage is programmed generate such an error,

What vi did you replace?

In my system the example loaded without errors

Re: Keithley 2400 Problems

First, the examples did not run because of wrong path directory . Hence I saved Keithley 24xx in instr.lib of labview 2013 . I chose current rang as 1 mA and voltage limit as 1 mV.

I'm a bit confused about using Labview with Keithley 2400. Does it need to send any command through communicator to keithley240xx ?

Because I thought , I just have to connect the keithley to my laptop and then run the Labview.

You are communicating to the instrument with LabVIEW so I don't understand your question.

One thing to check is if the driver is correctly using your local decimal settings. Try changing to a period and see if that makes a difference.

Albert.Geven — Mon, 13 Oct 2014 17:01:53 GMT

That are small lomits.
And indeed the driver is expected to be in the instr.lib.
If you installfrom labview it will automatically be installed there.

Hello People,

I am having the problem with the keythley 2400 sourcemeter. While working or measuring my solar devices this instrument is getting turned off and i have to switch it on again to work. Please suggest some solution...having hard time resolving it. 😞
